<a name="gstreamer-GstVersion.description"></a><h2>Description</h2>
<p>Use the GST_VERSION_* macros e.g. when defining own plugins. The GStreamer
runtime checks if these plugin and core version match and refuses to use a
plugin compiled against a different version of GStreamer.
You can also use the macros to keep the GStreamer version information in
your application.</p>
<p>Use the <a class="link" href="gstreamer-Gst.html#gst-version" title="gst_version ()"><code class="function">gst_version()</code></a> function if you want to know which version of
GStreamer you are currently linked against.</p>
<p>The version macros get defined by including "gst/gst.h".</p>
